Based on detailed analyses, cost-effective security programs that address the specific degree and nature of risk at specific airports can be designed and implemented. Various combinations of security measures are available and can be tailored for airport-specific or operator-specific security plans. These include various approaches to: surveillance and monitoring; airport access controls; and physical security measures to protect aircraft. These specific security systems implemented by airports and operators may be augmented by broader initiatives such as the vetting of GA pilots and airport workers at the federal level and establishing specific procedures and defenses to protect airspace near critical locations such as key federal facilities in Washington, DC. In the following discussion, these various approaches and the challenges associated with applying them to GA security are analyzed in further detail. 50 Transportation Security Administration.

Surveillance and Monitoring Surveillance and monitoring of GA operations is a challenge. Of the 5,286 public use landing facilities in the United States, only about 500 have operating control towers and most of these are located at airports with regularly scheduled commercial service. Only the busiest airports that cater exclusively to GA aircraft have operating control towers. These airports usually are geographically large and congested making surveillance for security purposes from the tower difficult. What’s more, even at the limited number of GA airports with operating control towers, most towers are not operated on a continuous basis and close during late night and early morning hours. While language in a Senate-passed amendment to the FY2006 DHS Appropriations bill (see S.Amdt. 1106 to H.R. 2360) would have required “an assessment of whether unmanned air traffic control towers provide a security or alert weakness to the security of general aviation aircraft”, the security role of staffed control towers is unclear. During operating hours, controllers remain busy performing air traffic separation and control functions, making it difficult for them to spot unusual activity or detect unauthorized aircraft usage unless suspicions are raised by unusual requests, improper phraseology, or procedural violations. Therefore, the mere presence of a operating control tower appears to provide little additional security to a GA airfield. 中国通航网 www.ga.cn 通航翻译 www.aviation.cn 本文链接地址：Securing General Aviation 通用航空安保(28) |
